The object of this, my present invention, is the construction of a humidifier for the wall registers of hot air furnaces which may be easily and quickly arranged upon or removed from the register and which has a water containing tank therein and further in which the construction is such that the major portion of heat from the register will be conducted through ducts or passages'that w surround the water receptacle to vaporize the water therein before the products can pass through the improvement.

To the attainment of the above broadly stated objects and many others which will present themselves the invention further consists in certain other novel features of con struction, combination and operative association of parts, one satisfactory embodiment of which is disclosed by the accompanying drawings.

In the drawings: Figure 1 is a sectional view through a chimney flue provided with a hot air register illustrating my improvement applied thereon, the improvement being also in section.

Figure 2.is' a top plan view of the improvement.

Figure?) is a front elevation thereof. Figure 4: is a sectional view approximately 3 on the line 4 4 of Figure 2.

Figure 5 is a rear elevation of the improvement.

In the drawings the numeral 1 designates a hot air conducting flue that leads from a suitable furnace. The fluehas arranged therein the box-like body 2 of a wall register, the outer face of the register being arranged preferably at an inclination and being apertured, as at 3. The outer face above and at the sides of the box-like body 2 is extended and formed with an inwardly directed flange 4 and upon this flange my improvement rests. The improvement is constructed r of any desired metal, copper preferred, and the same includes a body 5 which has its inner face open for the major portion of its length, its outer face rounded, as at 6, and its top arranged at an inclination, as at 7. The inclined top 7 has its rear edge formed with a downwardly directed flange 8 thatis arranged between the inner edge of the flange 4, the-front3 of the registerbox and the wall of the room. The open back 9 of the improvement rests against the top of the front face 3 of the register box. Thereis arranged in the improvement 5 a wat 1 container or tank 10 which, however, is preferably integrally formed with the 'body 5. The water container 10 has its rear wall 11 arranged at an outward angle with respect to the rear wall 9 of the body 5, so that the lower portion of the water receptacle is spaced from the said rearwall of the body. The outer face of the water receptacle, indicated by the numeral 12, isYarranged at the same curvature, asthe 6 front 6 of the body 5 but is suitably spaced I therefrom. The front wall 6 of the body 5 is provided with series of apertures 13, The top of the body 5 in which the pan or water receptacle 12 is arranged is flan ed inwardly to form the same with a shoulder 14 and on i this shoulder there is designed to rest the flanged edge of the closure member 15 for the pan or water receptacle 12. The closure 15 is hingedly secured, as at 16, tothe rear V of the top of the body'a-nd the said closure is apertured, as at 17. The closure is provided with a hand grip 18 whereby the same may be raised or lowered. The valve or shutter for the register is indicated by the numeral 19, the same in the present instance comprising a flat plate and has its outeredge hinged,

as at 20, to the top of the box or flange of the fap'ertured front 3 of the register. The damper plate or valve 19 1s provided with a hooked extension 21- which is pivot-ally securedtothe outer face of the said plate 19 and which passes through one of the apertures in the front plate 3, and the hook of this plate is designed to engage with the lower wall provided by the said aperture for hold- --ing-the plate at an inward angle, as disclosed by F igure 10f the drawings. The member 21, whenv moved out of the aperture and swung downwardly over the face plate 3 will hold the damper plate 19 in closed position.

The curved and apertured face 6 of the humidifier preferably has its bottom terminating a suitab-le distance away from. its back to provide a heat entrance opening 22.

It will be noted when the foregoing description has been carefully read in connection with the drawings that when the damper plate 19 has been swung to open position, as

5 disclosed by Figure 1 of the drawings the major portion of the hot air from the furnace will be directed through the open back of the humidifier and likewise directed between the outer face of the water receptacle or pan 12 and the outer curved face 6 of the humidifier so that the hot air will be effectively moistened before it enters the room in whim the improvement is arranged. The heat units will, of course, heat the water in the pan or receptacle 10 and thereby create a vapor which will escape through the apertured top 17 of the improvement.

While I have herein set forth a simple and satisfactory embodiment of my improve- 20 ment as it now appears to me I do not wish to be restricted to the precise construction disclosed and, therefore, hold myself entitled to make such changes therefrom as fairly 'hin the scope of what I claim.

,. dag described the invention, I claim:

1. A humidifier designed to be removably attached to the upper edge of a wall register for a hot air furnace, comprising a body having an open back, a curved front which is apertured and an inclined top which is partly open, a water receptacle in the body having an inclined rear wall which is gradually spaced away from the inner wall of said body and an outer wall which is struck at the same curvature as tne outer wall of the body, said water receptacle being disposed a distance below the open top of the body and providing, with said body, a continuous flange, said flange forming a seat for a flanged and apero tured closure which is hingedly secured to the open top of the body for covering the c pen top of the body and receptacle.

2. A humidifier designed to be removably attached to the upper edge of a wall register for a hot air furnace, comprising a body having an open back, a curved front which is apertured and an inclined top which partly open, a water receptacle in the body having an inclined rear wall which is gradually spaced away from the inner wall of the said body and an outer wall which is struck at the same cu 'vature as the outer wall of the body, said water receptacle being disposed a distance below the open top of the body, a

continuous flange between the open top of the body and the open top of the receptacle, said flange having a seat for a flanged and apertured cover and the curved front of the body, at its juncture with the open back thereof 60 having a transverse opening therethrough providing a heat inlet.
